Thanks for the link (Telford Television) ReeceyBurger123; there were nothing that power supply. Also thanks to budm by links to shopjimmy and ebay, TV has not damaged the resistance "R6536" as mentioned in ebay to buy the repair kit. Thank You for Your help. If anyone has the schematic of the power supply they are grateful.

I have potentially the same problem with Sony NSX-40GT1, 4.5 yrs. old looking for repair manual ( service manual available not needed to troubleshoot) which seems not to be available on any sites. Issue with tv was it went black & no sound, two blinking red lites ( 5 sec pause) where normally green. Checked power supply output @ 13 pin connector, only standby pin had correct 3v. No output voltage on other pins ( some are grounds), caps look good without testing, could transistors be failed or possible a voltage regulator? I can not find schematics for this tv. I do not think the tcon board is bad, main board not sure if ok either.

Sony GE4A Schematic is very close to this power supply.

Re: TV Sony NSX-40GT1 (Power Supply)

Thank you! I had the same blink pattern and this worked great for me. I ended up using TK5A50D MOSFETs as they were the recommended replacement for 2SK3563. I could not source the Panasonic part and used a 1/2 watt fusible resistor (Vishay NFR25H0004707JA500)

Thanks again!
